Despite being technically a demo, it was never re-recorded, and it features Beatles-influenced backing vocals from Tony Griffiths of the band the Real People.

"Supersonic" was written and recorded in a single day at the Pink Museum Studio in Liverpool,[1][2] on 19 December 1993.

[5] Guitarist Noel Gallagher claimed he wrote the song in half an hour,[1][6][nb 1] while his studio colleagues were taking a break from recording to eat a Chinese takeaway.

[9][10] Rather than joining them, Noel remained in the studio backroom working on his guitar riff and finished writing before they returned.

[11] Although Noel is credited as the sole songwriter,[12] he revealed in the 2004 documentary of Definitely Maybe that Bonehead and bassist Paul "Guigsy" McGuigan assisted him in writing the chords.

[1] Additionally, drummer Tony McCarroll wrote in his 2010 book The Truth: "Now, I know that Noel is the main songwriter for Oasis, but there were many instances like this where the band as a whole – and The Real People too – were integral to the composition of a song.

"[13][nb 2] McCarroll also recounted that Noel did not want to credit brothers Chris and Tony Griffiths of the Real People as co-producers of "Supersonic" or feature the band itself as a guest act on any future Oasis performance, leading to a verbal altercation between Noel and singer Liam Gallagher as well as constant problems with the rest of the band members.

[14] Following a short local tour with the Verve, Oasis performed at the Krazy House club in Liverpool, supporting the Real People, on 16 December 1993.

[15] After the gig, they booked sessions at the Pink Museum with Coyle and engineer Dave Scott for a few days,[16][nb 3] funded by £300 per day,[20] to record "Bring It on Down" for release as their then-upcoming debut single, at the request of Creation Records owner Alan McGee.

"[9] According to Scott, Oasis attempted to record a studio version for "I Will Believe", but he dismissed the result because it sounded like an early 1980s indie pop song.

[23] Meanwhile, Scott asked the Griffiths brothers, who were present at the sessions, to give Oasis musical and technical advice.

[17][19] Instead of recording B-side songs,[20] Tony Griffiths suggested them to develop their jam as it had the potential of a hit single.

[23][24] After Tony's suggestion, Noel went to the corner and quickly wrote down the lyrics, and then Oasis began recording "Supersonic".

[19] Noel played an Epiphone Les Paul guitar through a Watkins Dominator MKIII combo amp.

[28][nb 6] Although it was originally based as a demo, it was never re-recorded, and this refers to producer Owen Morris, who later reworked on some other tracks on Definitely Maybe prior to its release.

[36] Along with the Definitely Maybe song "Live Forever", the basic rock rhythm of "Supersonic" is reminiscent of early 1970s music.

[39] The song is played in the key of F♯ minor in a 44 time signature with a tempo of 104 beats per minute (BPM),[40] while Liam's vocals span a range of E3 to F♯4.

[28] The lyrics are often regarded as a distillation of "lumpen" nonsense poetry, with "forced" doggerel rhymes and "half-baked" allusions in multiple lines throughout the song,[46] such as "I'm feeling supersonic / Give me gin and tonic",[47] "He lives under a waterfall / Nobody can ever hear him call",[48] "I know a girl called Elsa / She's into Alka-Seltzer",[47] "And she makes me laugh / I got her autograph",[49] "She done it with a doctor, on a helicopter" and "She's sniffing in a tissue, selling the Big Issue".

[64] "Supersonic" debuted on the UK Independent Singles Chart at number three on 30 April 1994, behind "Always" by Erasure and "The Most Beautiful Girl in the World" by Prince, respectively.

[74] It also reached number 38 on the Billboard Album Rock Tracks chart on the issue dated 24 December 1994.

[86][87] On 19 April 2014, "Supersonic" was reissued as a remastered 12-inch single by Big Brother, as part of the 2014 Record Store Day.

[64] On 12 April 2024, "Supersonic" was reissued on CD, as well as a limited edition, numbered and pearl-colored 7-inch vinyl to mark the 30th anniversary of its release.
